Comparison of cognitive workload between very short answer questions and multiple-choice questions: an eye-tracking experiment.
Trial report in Medical education online, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Very short answer questions (VSAQs) have gained attention for their superior psychometric properties compared to multiple-choice questions (MCQs). While VSAQs require knowledge recall, MCQs primarily involve knowledge recognition. This difference in cognitive processes may lead to varying cognitive workloads, defined as the amount of mental processing in working memory. Previous studies have not demonstrated consistent differences, likely due to reliance on self-reported measures. Eye tracking provides objective, process-level indicators of cognitive workload. This study investigated whether answering VSAQs requires a higher cognitive workload than answering MCQs. In a within-subject randomized crossover experiment, sixth-year medical students answered both VSAQs and MCQs. Cognitive workload was measured using screen-based eye tracking, focusing on the number of fixations and revisitations as objective indicators of mental effort. Data were analyzed using mixed-effects models. Thirty-four medical students participated, yielding 1,326 observations, which is the multiplication of the number of students by the number of questions (39 questions). Mixed-effects models showed a significant effect of question type on both workload indicators: VSAQs elicited more fixations and revisitations than MCQs (β_std = 0.30-0.39,
